Description
Overview:
This Genuine Stihl throttle lever is the OEM control trigger that restores smooth, accurate engine speed control on compatible Stihl handheld machines such as the FS 40 and FS 50 brushcutters. Moulded from high‐strength polymer for durability, it sits inside the handle and actuates the throttle cable, giving precise modulation from idle to full power. Built to Stihl's 4144 platform specification, manufacturer part number 4144 121 3501 matches the original geometry for a secure fit and reliable operation. It is designed for selected Stihl brushcutters, edgers, pole pruners, hedge trimmers, KombiEngines and MultiSystem units within the same family. Use it to replace a worn, cracked, sticky or missing lever and restore positive control, consistent performance and safer handling during cutting and trimming work.
